SPECIALTY: For more than 35 years, NYC-based Rothenberg has been shaping the arches and de-fuzzing the faces of real world Gossip Girls (and more than a few incognito dermatologists) who appreciate her ultragentle, no-redness approach.

SECRET WEAPON: Ask about her brow boot camp: After coaxing your arches into line and monitoring their growth for a few months, she'll use a combo of laser and electrolysis to set the shape. "The follicle creates a shadow that can make your eyebrow look heavy. Plucking only removes the hair; laser erases it."

QUICK FIX: Removing peach fuzz on the sides of the face will emphasize your cheekbones. "That hair catches the light and can make your face look more round and less defined."
